Poisoning due to Abrus precatorius (jequirity bean).

Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products. In industry, the principal use of hydrogen peroxide is as a bleaching agent in the manufacture of paper and pulp. Hydrogen peroxide has been employed medicinally for wound irrigation and for the sterilisation of ophthalmic and endoscopic instruments. Hydrogen peroxide causes toxicity via three main mechanisms: corrosive dama

Triclosan/copolymer containing toothpastes for oral health.

BACKGROUND: Periodontal disease and dental caries are highly prevalent oral diseases that can lead to pain and discomfort, oral hygiene and aesthetic problems, and eventually tooth loss, all of which can be costly to treat and are a burden to healthcare systems. Triclosan is an antibacterial agent with low toxicity, which, along with a copolymer for aiding retention, can be added to toothpastes to reduce plaque and gingivitis (inflammation of the gums). It is important that these additional ingredients do not interfere with the anticaries effect of the fluoride present in toothpastes, and that…

Uterine-sparing Laparoscopic Resection of Accessory Cavitated Uterine Masses.

STUDY OBJECTIVE: To demonstrate surgical techniques utilized during uterine-sparing laparoscopic resections of accessory cavitated uterine masses (ACUMs). ACUMs represent a rare uterine entity observed in premenopausal women suffering from dysmenorrhea and recurrent pelvic pain. The diagnosis is made when an isolated extra-cavitated uterine mass is resected from an otherwise normal appearing uterus with unremarkable endometrial lumen and adnexal structures. Pathologic confirmation requires an accessory cavity lined with endometrial epithelium (and corresponding glands and stroma) filled with c

Zirconia implants: a promising alternative to titanium?

Design This study is a monocentre cohort study with a primary aim to assess the five-year survival of alumina-toughened zirconia (ATZ) implants (Metoxit AG, Thayngen, Switzerland). Secondary aims were to evaluate peri-implant marginal bone loss (MBL), soft tissue health and patient-reported outcome measures (PROMs). The implants were placed into healed ridges and, following a period of temporisation, were restored with either IPS e.max CAD LT or IPS e.max ZirCAD veneered with IPS e.max ZirPress (Ivoclar Vivadent, Schaan, Liechtenstein). Patients were followed up at prosthetic delivery, one-yea

Relationship between tooth extraction and development of medication-related osteonecrosis of the jaw in cancer patients.

Tooth extraction has been avoided since it has been considered a major risk factor for medication-related osteonecrosis of the jaw (MRONJ). However, MRONJ may also develop from tooth that is an infection source. This study aimed to clarify whether tooth extraction is a risk factor for the development of MRONJ in cancer patients receiving bone-modifying agents (BMAs). This retrospective observational study included 189 patients (361 jaws) from two hospitals. The risk factors of MRONJ were identified by comparing patient characteristics between those who did and did not develop MRONJ. Furthermor

The Influence of Local Pamidronate Application on Alveolar Dimensional Preservation after Tooth Extraction-An Animal Experimental Study.

The aim of this randomized, controlled animal exploratory trial was to investigate the influence of local application of aminobisphosphonate pamidronate during the socket preservation procedure. Mandibular premolars were extracted in five Göttingen minipigs. Two animals underwent socket preservation using BEGO OSS (n = 8 sockets) and three animals using BEGO OSS + Pamifos (15 mg) (n = 12 sockets). After jaw impression, cast models (baseline, eight weeks postoperative) were digitized using an inLab X5 scanner (Dentsply Sirona) and the generated STL data were superimposed and analyzed with GOM I

Prevention of medication-related osteonecrosis of the jaw after tooth extraction by local administration of antibiotics and atelocollagen sponge: A preliminary study.

BACKGROUND/PURPOSE: Medication-related osteonecrosis of the jaw (MRONJ) often develops after extraction of a tooth with a local infection. Therefore, it is necessary to develop extraction methods that can prevent MRONJ. Before examining whether antibiotics and atelocollagen administered in the extraction socket can prevent the development of MRONJ after tooth extraction, this study was conducted to determine the appropriate antibiotics concentration and to conduct a clinical study with a small number of cases as a preliminary study. MATERIALS AND METHODS: First, a mixture of minocycline and a

Should oral foci of infection be removed before the onset of radiotherapy or chemotherapy?

Pretreatment dental screening aims to locate and eliminate oral foci of infection in order to eliminate local, loco-regional, or systemic complications during and after oncologic treatment. An oral focus of infection is a pathologic process in the oral cavity that does not cause major infectious problems in healthy individuals, but may lead to severe local or systemic inflammation in patients subjected to oncologic treatment. As head and neck radiotherapy patients bear a lifelong risk on oral sequelae resulting from this therapy, the effects of chemotherapy on healthy oral tissues are essentia

Endodontic therapy and Medication-related osteonecrosis of the jaw onset: a scoping review and expert opinion-based qualitative meta-synthesis.

INTRODUCTION: Medication-related osteonecrosis of the Jaw (MRONJ) is a serious side effect of bone-modifying agents (BMAs), including bisphosphonates, denosumab, and antiangiogenic drugs. Some dental procedures are recognized as local risk factors for MRONJ. Given the lack of specific guidelines for root canal therapy in patients treated with BMA, this scoping review aimed to investigate the risk of MRONJ associated with failed root canal therapy. Subsequently, a meta-synthesis of expert opinions was performed to identify existing recommendations and pitfalls of root canal therapy in patients

… In our opinion, a thorough analysis of the criteria for endodontic therapy in patients at risk of MRONJ is essential since, under normal conditions (in the absence of BMA therapy), failure of root canal therapy may lead to tooth loss, but in patients taking BMAs it could also be a trigger for MRONJ. …

A 5-year retrospective cohort study of denosumab induced medication related osteonecrosis of the jaw in osteoporosis patients.

Denosumab has been suggested as a first-line therapy for osteoporotic patients. However, a standardized protocol for the prevention of denosumab induced medication-related osteonecrosis of the jaw (MRONJ) has not yet been established. The purpose of this study was to report denosumab induced MRONJ cases, and investigate the factors affecting the occurrence of MRONJ in patients who underwent denosumab and invasive dental treatment (especially tooth extraction) between October 2016 and March 2020. Four of the 98 patients developed MRONJ before and after tooth extraction. The participants were di

Calcium Phosphate Ceramics Can Prevent Bisphosphonate-Related Osteonecrosis of the Jaw.

Bisphosphonate-associated osteonecrosis of the jaw (BRONJ), a post-surgical non-healing wound condition, is one of the most common side effects in patients treated with nitrogen-containing bisphosphonates. Its physiopathology has been related with suppression of bone turnover, of soft tissue healing and infection. Biphasic calcium phosphates (BCP) are used as a drug delivery vehicle and as a bone substitute in surgical wounds. Due to their capacity to adsorb zoledronate, it was hypothesized these compounds might have a protective effect on the soft tissues in BRONJ wounds. To address this hypo
